Angostura Bitters is a concentrated herbal mixture used primarily as a flavoring agent in cocktails and culinary dishes. It was created in the early 19th century by Johann Gottlieb Benjamin Siegert, a German doctor, in the town of Angostura, Venezuela. The bitters are made from a blend of herbs, spices, and other botanicals, giving them a unique and complex flavor profile. Typically, Angostura Bitters is used in small quantities, often just a few dashes, to enhance the taste of drinks like the Old Fashioned and Manhattan. It is also popular in non-alcoholic beverages and can be used in cooking to add depth to sauces and marinades.
